Geranium plant named ‘Tosdynsal’

ABSTRACT

A new and distinct cultivar of Geranium plant named ‘Tosdynsal’, characterized by its semi-double type, medium salmon-colored flowers, medium green-colored foliage having zonation, and moderately vigorous, upright-mounded growth habit, is disclosed.

Latin name of genus and species of plant claimed: Pelargonium×hortorum.

Variety denomination: ‘Tosdynsal’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant botanically known as Pelargonium×hortorum and hereinafter referred to by the cultivar name ‘Tosdynsal’.

The new cultivar originated in a controlled breeding program in Weener-Halte, Germany during July 2005. The objective of the breeding program was the development of Geranium cultivars that flower uniformly with attractive flower coloration and a moderately vigorous, upright-mounded growth habit.

The new Geranium cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is ‘Sil Sören’, not patented, characterized by its double-type, light salmon-colored flowers, dark green-colored foliage having zonation, moderate to low growth vigor, and upright-mounded growth habit. The male (pollen) parent of the new cultivar is PAC Calais ‘Paclai’, U.S. Plant Pat. No. 16,751, characterized by its semi-double type, salmon-pink colored flowers, medium green-colored foliage, and moderately vigorous, compact, upright-mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during June 2006 in a controlled environment in Weener-Halte, Germany.

Asexual reproduction of the new cultivar by terminal stem cuttings since June 2006 in Weener-Halte, Germany and Arroyo Grande, Calif. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Tosdynsal’ as a new and distinct cultivar of Geranium plant:

-   -   1. Semi-double type, medium salmon-colored flowers;     -   2. Medium green-colored foliage having zonation; and     -   3. Moderately vigorous, upright-mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower type, shade of flower color and shade of foliage color. Plants of the new cultivar differ from plants of the male parent primarily in shade of flower color and in having a smaller diameter corolla.

Of the many commercially available Geranium cultivars, the most similar in comparison to the new cultivar is AMERICANA Salmon ‘Amri Sal09’, U.S. Plant Pat. No. 20,452. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Amri Sal09’ in at least the following characteristics:

-   -   1. Plants of the new cultivar are taller as measured to top of         plant plane than plants of ‘Amri Sal09’; and     -   2. Plants of the new cultivar have more total inflorescences per         plant than plants of ‘Amri Sal09’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Tosdynsal’. The plants were grown in 4.5-inch pots for 9 weeks in a greenhouse in West Chicago, Ill.

FIG. 2 illustrates a close-up view of an individual umbel of ‘Tosdynsal’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in April 2013 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4.5-inch pots for 9 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
